The U.S. Postal Service lost $1.2 million as a result of printing 1 billion Simpsons stamps yet only selling 318 million. This failure was used in a report scrutinizing the USPS’s practice. Maybe they messed up – maybe The Simpsons aren’t as popular as we all thought – maybe people who were raised watching The Simpsons just don’t use stamps anymore. Really, who uses stamps!? Who mails things? And who’d send some important government/medical document with a stamp of Homer screaming on it? (Barbara Bush, maybe.)
